Subject: [PATCH RESEND] arm64: dts: ti: k3-am62-main: Add gpio-ranges properties
Date: Mon, 27 Nov 2023 12:26:57 +0100	[thread overview]
Message-ID: <20231127112657.2692103-1-rwahl@gmx.de> (raw)

From: Ronald Wahl <ronald.wahl@raritan.com>

On the AM62 platform we have no single 1:1 relation regarding index of
gpio and pin controller. Actually there are some linear ranges with
small holes inbetween. These ranges can be represented with the
gpio-ranges device tree property. They have been extracted manually
from the AM62x datasheet (Table 6-1. Pin Attributes).
